Teranex Mini IP Video 12G - communication ports question

PostFri May 20, 2022 9:42 am

Hello!


Teranex Mini IP Video 12G - which ports are in use for communication over network between device and Teranex Setup/Videohub control software.
The problem is that when IP Video devices are connected locally to PC through Gigabit switch , the Teranex Setup is able to find them over network . But when devices are connected to our production network through Cisco WS-C2960S-48TS-L switch then the devices are streaming video OK, but not accessible through network . So we suppose some ports are closed within our network , so the question which port is using IP Video device to communicate with Teranex Setup software?

I believe the discovery of Teranex Mini units uses multicast DNS (mDNS) along the lines of what is used for Bonjour and other zeroconf protocols. mDNS uses UDP port 5353, however, UDP multicast is often confined to a local network by default and not forwarded across subnets or out to the WAN.

How to enable routing of UDP multicast mDNS traffic beyond a subnet will depend on the network configuration and network hardware, but Cisco has a number of guides for this for their products, such as:
https://content.cisco.com/chapter.sjs?u ... y.html.xml

Once the IP address of the Teranex Mini unit is discovered, it seems like any configuration changes performed through the Teranex Setup utility are then sent over TCP port 9996 to the selected device.
